PCALX Roaming Calibration Line Frequency Changed from 4801.3 to 5001.3 Hz
J. Kissel for S. Karki

I've moved the roaming calibration line to its highest frequency we intend to go, and it's also the last super-long duration we need. We may run through the lower frequency points again, given that (a) they need much less data, and (b) those data points were taken at various input powers that will likely confuse/complicate the analysis. Below is the current schedule status.

Before the HW injection test, we turned off this line (before entering observation intent). I turned it back on at Nov 23 2016 03:25 UTC, but this did not drop us out of observation intent.

This line was again turned off at 4:12 Nov 23 2016 UTC so that DetChar safety study can be made late tonight.

The analysis of sensing function at frequency above 1 kHz obtained from the roaming lines listed in the alog above is attached.  These lines were run at different times than the low frequency sweep (below 1 kHz) taken on Nov 18 and included in this plot. So, the lines above 1 kHz will need to be compensated for the time varying parameters to make accurate comparison and has not been done for this plot.

One way of compensating the changes are by applying kappas calculated using the SLM Tool (or GDS). The other way of doing it is comparing each individual line with 1083.7 Hz (which is always on) line at time t (time at which each line is running)  and time t0 (time of low freqeuncy sweep).

Sensing Function [ct] /[m] = (DARM_ERRR/TxPD) f= hf, t  * (TxPD/DARM_ERR) f = 1083.7, t * (DARM_ERRR/TxPD) f= 1083.7, t0

Both methods are essentially same but I will use the second method and the plot with the correct compensation applied to come soon.
